Abstract

The invention is applicable to the field of communication technology, and provides a UDP multicast method, a system, a sending device and a receiving device. The UDP multicast method includes: a sending device obtains a message to be sent, and assigns a message sequence number to the message to be sent; the sending device divides the message to be sent into a plurality of message fragments, and assigns a fragment to each message fragment Slice serial number; the sending device sends the message fragment to the receiving device, and the message fragment carries the unique identifier of the sending device, the message serial number and the fragment serial number; the receiving device establishes a secondary buffer area, and passes the secondary buffer area Cache the message fragments; when the receiving device completes receiving all the message fragments corresponding to any message sequence number, it extracts all the message fragments corresponding to the message sequence number from the secondary buffer area. The invention realizes efficient data packet loss detection, can deal with the disorder of data packets, reduces time complexity, and improves the reliability and stability of UDP multicast.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a UDP multicast method, system, sending device and receiving device. Background technique [0002] In the prior art, the transport layer on most operating systems adopts TCP (Transmission Control Protocol, Transmission Control Protocol) to realize reliable point-to-point communication. When it is necessary to realize reliable communication among a group of processes, the implementation method on most application layers is to establish a point-to-point connection between each process communicating with it for each process. Obviously, this communication method of process group consumes a lot of time Bandwidth, less efficient. In the prior art, although UDP (User Datagram Protocol, User Datagram Protocol) multicast can implement multicast between process groups, it cannot guarantee reliable data transmission. In addition, UDP packets are limited by the data lengt...
